In what type of polygon is the sum of the measures of the interior angles equal to 1260 degrees?
(2n - 4) x 90 = 1260 where n is the number of sides.ie 180n = 1260 + 360n = 1620/180 = 9Your polygon is a nonagon (or enneagon)
What is the sum of the measures of the angle in a nonagon?
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1260 degrees
What is the number of sides of a polygon if the sum of the measures of its angles is 1260 degrees?
Suppose the polygon has n sides. Then (n - 2)*180 = 1260 So (n - 2) = 1260/180 = 7 and therefore, n = 7 + 2 = 9
What is the sum of measure of a nonagon?
A nonagon is a 9 sided polygon and its 9 interior angles add up to 1260 degrees
One exterior angle of a regular polygon measures 40 What is the sum of the polygons interior angle measures?
1260 degrees
